Definitions

  • the invention relates to a belt buckle for a belt system with a lap belt and two shoulder belts, wherein one end of the lap belt is attached to a metal frame framed by the lock housing and the other end of the lap belt is connected to a metallic lock tongue which can be plugged into the lock housing and can be locked to the frame by means of a lock that can be released manually by means of a button, while end pieces are provided for fastening the shoulder strap ends, which are plugged in alignment on a common holding part when the buckle is in the closed position.
  • a known buckle of this type enables the webbing end pieces to be plugged onto a common holding part, these end pieces being secured against sliding off the holding part after the lock tongue has been locked in the lock housing.
  • the holding part is part of the lock frame which is essentially clad by the lock housing, it requires considerable space because it must be provided outside the actual lock housing.
  • the lock housing has a mechanism consisting of a relatively large number of individual parts, with the aid of which a strap end piece is locked in a form-fitting manner on the tether. This mechanism causes correspondingly high manufacturing costs because of its individual parts, and there is a risk that the functional safety, in particular the unlocking of the belt end pieces in an emergency, is endangered due to wear of these parts.
  • the plugging together of the belt buckle is still in need of improvement, since at least one of the plugged-on end pieces is particularly firmly held when the buckle tongue is inserted must, which leads to cumbersome handling of the buckle.
  • the lock tongue can be locked even if not all of the webbing end pieces are attached to the holding part mentioned, the locking process of the lock tongue also possibly requiring additional manipulations and thus also making the lock operation difficult.
  • the object of the invention is to provide a belt buckle of the type mentioned in the introduction, which is further simplified in its construction, is more compact in design, is easier to operate and made safer, and is improved with regard to the latching of the buckle tongue.
  • the solution to this problem is based on the specified buckle and is characterized in that the belt end pieces are aligned with one another with their attachment slots in a system defined by positive locking, that the buckle tongue can be inserted from one side through the slots and that on the other Side protruding from the plug-in slots of the tongue in the housing can be locked after at least one control member provided on the belt end piece adjacent to the housing has released its locked position by adjusting a spring-loaded latch.
  • the structure of such a buckle is further simplified and more compact, since there is no need for a correspondingly large common holding part for the strap end pieces on the buckle housing. Instead, the end pieces sit on a relatively short section of the lock tongue.
  • the operation, in particular the plugging together of the lock is simplified in that the strap end pieces are first coupled together and thus plugged onto the lock tongue, which then latches and tears with the rest of the lock is valid, which can be carried out easily and quickly, the interconnected end pieces and the lock tongue can be easily held and guided by hand during the locking process.
  • the locking of the lock tongue in the rest of the lock is designed to be safer in that the tongue cannot be easily or lightly brought into its locked position, but this is only possible after the locking position has been released by a bolt. However, this is only activated when both webbing end pieces are seated in the correct position on the tongue, since one of the end pieces has the control element adjusting the bolt.
  • the buckle shown consists of the Lock housing 1, which contains the usual locking and release mechanism inside, which is explained in more detail below, from the lock tongue 2 and at least from the two end pieces 3 and 4 for attachment to the ends 5 of shoulder straps, not shown.
  • the end pieces 3 and 4 which are preferably made entirely of plastic, have, in addition to the usual areas for fastening the shoulder straps, two arms 6 and 7 facing the buckle parts 1 and 2, each arm having a slot 8 and 9, respectively. These slots are aligned with one another when the arms 6, 7 are brought into abutment against one another in their predetermined operating position, as can be seen from FIGS. 1 and 2.
  • the lock tongue 2 is inserted through these slots, the two arms 6, 7 then coming to rest on the section 2a of the tongue 2.
  • the section 2b of the tongue 2 extends in the usual way into the lock housing 1 and engages in it. 2 shows how the arms 6 and 7 sit on the section 2a, the section 2b of the tongue 2 protruding on the other side of the slots, so that this section can be inserted into the lock housing 1.
  • the lock tongue 2 is known in its remaining structure, so that it need not be explained further.
  • the section 2a of the lock tongue 2 is tapered according to FIG. 1 in the plug-on direction of the tongue, and this is likewise the case with the plug-in slots 8 and 9 of the arms 6 and 7, respectively. This avoids that the lock tongue 2 can be locked in the lock housing 1 with only one attached end piece or with an incorrectly attached end piece. If the case arises that the end piece 4 is only plugged onto the section 2a, then ultimately the lock tongue 2 cannot be locked, since due to the play between the section 2a and the insertion slot 9 of the arm 7, this arm is at least is pushed back so far that the control elements 10 provided on the housing side thereof cannot yet become fully effective, so that the tongue section 2b cannot be locked.
  • the arm 6 of the one webbing end piece 3 is provided with a web 11 which extends laterally from the arm 6 and according to FIGS. 1 and 2 over the arm 7 of the other end piece 4 .
  • This web 11 is provided with a projection 12 which positively engages in a corresponding recess 13 in the arm 7 of the other end piece 4.
  • the web 11 and the projection 11 provided on it and the recess 13 extend — seen in the insertion direction of the lock tongue 2 — transversely to the tongue and are at a distance from it.
  • the projection 12 and the recess 13 are designed in the form of a tongue and groove configuration
  • other form-locking configurations can also be used, e.g. a pin that engages in a corresponding recess. It is also possible; .that the projecting positive locking means on the arm 7 and the receiving positive locking means is provided on the arm 6.
  • the arm 7 of the belt end piece 4 has two projecting control members 10. These tax organs come to rest when the lock tongue 2 is inserted into the lock housing 1 against the two legs 14a of a U-shaped latch 14, which is preferably made of plastic, and press the latch back, as can be seen from FIGS. 5 and 6.
  • the bolt 14 preferably has two locking lugs 15 which extend in the direction of the insertion slot of the lock housing 1, namely in the locked position of the bolt 14 to such an extent that they block the entrance to the locking position of the lock tongue 2, as best shown in FIG 6 can be seen.
  • the procedure for unlocking the lock tongue 2 and thus also the belt end pieces 3 and 4 is as follows.
  • a button 18 is depressed by finger pressure, whereby the angular hold-down device 17 is pivoted back against the force of a spring, not shown, so that the web 2c of the lock tongue 2 is released and can be ejected.
  • an integrated, tongue-like auxiliary spring 19, preferably made of the material of the lock housing 1, is provided, which extends through a corresponding recess 20 in the frame 16 and bears against the web 2c of the tongue 2.
  • This auxiliary spring causes a safe ejection of the lock tongue from its latched position, the downholder 17 pivoting forward again finally ejecting the lock tongue from the housing 1.
  • the bolt 14 is also pushed back into its locked position, which can be seen in FIGS. 1 and 6, by means of a spring 21.
  • two webbing end pieces 3 and 4 are used, which are attached to the ends of shoulder straps.
  • a crotch strap with an end piece, which also has an arm, which is then pushed together with the arms 6 and 7 of the end pieces 3 and 4 onto the correspondingly longer section 2a of the lock tongue 2.
  • Such a buckle is also compact and light in structure, easy to use and also functionally reliable.
  • the rest of the construction of the belt buckle in this case is as described above, and it should also be mentioned that the ends of the lap belt are fastened to the buckle tongue and the buckle housing in the usual way.
